Reminder of Forthcoming Release Procedures Changes

Following the release of 4.100 we will change to releasing only 4.yyy and 4.yyy.zz
releases on the master branch.

Intermediate work such as general bug fixing and feature enhancement will
move to the 4.next branch.  We will endeavour to apply any .zz security
fixes to the 4.next branch in a timely manner though there may be some lag.

Release candidates for 4.yyy+1 (4.101 onwards) will be tagged on the 4.next branch.
